Aldehyde/benzene-removing radiation-resistant inner wall putty powder

Abstract

The invention discloses an aldehyde / benzene-removing radiation-resistant inner wall putty powder which is composed of the following raw materials in parts by weight: 14-18 parts of ground calcium carbonate. 8-12 parts of talcum powder, 10-14 parts of white cement, 4-6 parts of gypsum powder, 6-8 parts of meerschaum powder, 5-7 parts of bamboo charcoal powder, 3-5 parts of nano porous silicon dioxide, 1-2 parts of zinc oxide micropowder, 4-6 parts of conductive powder, 4-6 parts of lignocellulose, 2-3 parts of alpha-starch, 0.5-1.5 parts of inorganic antimicrobial powder, 3-5 parts of thickening agent, 7-9 parts of binding agent, 2-3 parts of fiber, 0.7-0.9 part of dispersing agent, 0.6-0.8 part of defoamer, 2-3 parts of ethylene glycol and 20-30 parts of water. The putty powder disclosed by the invention not only has the conventional properties of the common putty powder, but also has the functions of aldehyde / benzene removal and radiation resistance.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an anti-radiation interior wall putty powder for removing aldehydes and benzene. Background technique [0002] With the development of the economy, people have higher and higher requirements for the beauty of the interior, and the personal aesthetic requirements are met through the decoration of the interior environment, and the environmental pollution caused by interior decoration is becoming more and more serious. Formaldehyde, volatile organic compounds benzene and toluene released from decoration materials and paints. In addition, in the process of interior decoration and renovation, a large amount of phenolic resins, floor furniture paints, wallpapers, paint thinners, etc. are used. Once such substances are exposed Formaldehyde is released, causing the concentration of formaldehyde in the air of the family room to reach 0.05-2mg / m 3 . According to the spot check...

Problems solved by technology

For example, the Chinese invention patent application number 200610134425.7 overcomes the disadvantages of ordinary wall putty such as cracking and falling off, but there is no better solution to the colloid containing a large amount of organic solvents such as formaldehyde and benzene, and there are still irritating odors and serious pollution. Indoor air, causing great harm to the human body and other deficiencies

For example, the Chinese Invention Patent Publication No. CN101215433A, the title of the invention "Multifunctional Putty Powder and Its Preparation Method" introduces a natural raw material, reasonable formula, high crack resistance, high compressive strength, waterproof and scrub resistance, non-toxic and tasteless, Antibacterial and other characteristics, many functions, strong performance, stable performance and easy construction, simple production process, as long as various raw materials are fully mixed and stirred, it can be prepared, and it has no adverse effects on the environment during the production process. Because only the multifunctional putty powder itself has the characteristics of high crack resistance, high compressive strength, waterproof and scrub resistance, non-toxic, tasteless, antibacterial, etc., it cannot effectively remove formaldehyde and electromagnetic radiation, and it cannot remove indoor air pollution. It cannot prevent mildew, release negative ions and resist electromagnetic radiation, and these air pollutions are very harmful to humans
